IMPROVEMENT IN CLEARING ATTACHMENTS FO R CARDlNG-MACHINES.

Specification forming part of Letters Patent No. 205,805, dated July 9,1878; application filed November 30-, 1877.

To all whom it may concern:

Be it known that I, EG-TDI MOOG, of Oggersheim, in the Kingdom ofBavaria and Empire of Germany, have invented a new and Improved ClearingAttachment to Garding-Machines, of which the following is aspecification:

In the accompanying drawing, Figure 1 is a sectional elevation of theclearing attach- .ment on a large scale. Fig. 2 is a front view of aportion of the same. Fig. 3 is a section of a carding-machine on a smallscale, showing position of my improved attachment in relation to themain cylinder, top cards, and doffer.

Similar letters of reference indicate correspondin g parts.

The invention relates to a clearing attachment for carding-machines,which is designed to be placed into the space between the top cards,doffer, and main cylinder of the machine for acting on the surface ofsaid cylinder.

The invention consists in the construction of the attachment and themeans for supporting the same in position, as will be hereii'iafter morefully described, and then set forth in the claims.

By referring to the drawing, A represents the main cylinder, 13 the topcards or top flats, and O the doffer, of a carding-machine of the usualconstruction.

In the triangular space formed between main cylinder, top cards, anddoffer I arrange my improved clearing attachment, which consists ofscraping-knives D, which are attached to wooden rails or blocks D, thatare let into recesses of the cast-iron side pieces 1) of the attachment.The knives and rails extend the whole length of the main cylinder, andare placed at an angle of about forty-five degrees to the circumferenceof the same.

The scraping-knives D are made of steel plates of suitable thickness,and well hardened to prevent their wearing out, they being provided witha sharp edge at the end next to the cards of the main cylinder.

The knives D are adjusted nearer to or farther from the main cylinder bymeans of regulating-screws a, which pass through the side pieces D andbear on the rear parts of the sliding rails D. By the use of thesescrews one or all of the knives maybe regulated with the greatest casewhile the machine is at work. The degree of adjustment has to beaccording to the length and quality of the cotton, and has to bedetermined by actual tests in each case.

Below the lowermost knife-block is arranged a wooden connectingrpiece,E, of triangular shape, which serves to fill out the empty space betweenthe main cylinder and dofier, and to support the collecting-trough E.

The entire clearing attachment is supported on arms F, which are pivotedby their upper ends to the upper parts of the side pieces D and appliedby their lower forked ends to fixed bolts 1) of the side frame of thecardingmachine. The arms F swing on the bolts b,

and serve to cary the attachment into posi-' tion toward the maincylinder.

The side pieces D bear by side flanges on wood-screws d, that arescrewed into the lining between the main cylinder and the frame of thecarding-machine, the wood-screws retaining the clearing attachment atthe proper distance from the cards.

To the side frame of the carding-machine is attached a wooden casing, F,or dust-cover, that extends over the entire apparatus and back to thedoffer, the cover being made of a fixed section, attached to the concaveshell of the top flats, and of a hinged section that may be convenientlythrown up for the purpose of adjusting the scraping knives or entireattachment.

This clearing mechanism may be attached with equal facility to old ornew carding-machines by merely screwing the supportingbolts andregulatingscrews in position, and placing then the attachment inposition on the same.

The scraping knives serve to detach the tufts and knots from the cottonforced against them by the cards of the main cylinder, and to collectthem in the trough, which is emptied from time to time by taking off theentire device from its supports. Any adhering impurities that escape thetop cards are thus reliably removed by the clearing attachment, and amore uniform fleece or layer of cotton furnished for the successivetreatment.

Having thus described my invention, I claim as new and desire to secureby Letters Patattachment D D D E, for adjustably hangentin g saidattachment to the frame of a carding- 1.
